“…These high values, together with the greatly elevated faecal mass of bacteria in that experimental group, are consistent with the high content of fermentable non-cellulosic polysaccharides in that fraction compared with the WB and PC diets. As expected, concentrations of VFA and the mass of bacteria in faeces were low in rats fed on a-cellulose (diet C), observations which accord with the fact that this polysaccharide is metabolized quite poorly by the large bowel microflora of the rat (Lang & Briggs, 1976). However, the relations between dietary plant fibre and bacterial fermentation and its products are not entirely simple.…”

“…Levels were significantly ( P < 0-05) lower (pmol/ml) in the PC (3.51 (SE 0-16)), WB (3.49 (SE 0.17)) and C (3.20 (SE 0.17)) groups, none of which differed from each other. , 1973;Bacic & Stone, 1981 h). The amount of this latter component associated with wheat bran depends on the milling regime but in the bran from 'high extraction' milling (such as used in the present study) it is low.…”

Comparative effects of dietary wheat bran and its morphological components (aleurone and pericarp-seed coat) on volatile fatty acid concentrations in the rat

1. Adult male rats were fed on diets containing 100 g dietary fibre/kg either as a-cellulose or wheat bran or the pericarp-seed coat or aleurone layers prepared from that bran by sequential milling and air elutriation and electrostatic separation.2. After 10 d, concentrations of total volatile fatty acids (VFA) in caecal fluid were significantly different between groups and fell in the order: aleurone > wheat bran > pericarp-seed coat > cellulose. This ranking probably reflected the ease of fermentation of fibre polysaccharides by colonic bacteria which also resulted in a considerably higher faecal bacterial mass in the aleurone group.3. Because of the differences in the volume ofcaecal digesta, the mass of caecal VFA was considerably the highest in the aleurone group, intermediate with wheat bran and equally low in the pericarp-seed coat and cellulose groups.4. The diet based on aleurone gave a relatively higher proportion of propionate but with both pericarp-seed coat and wheat bran the contribution of butyrate was raised.5. VFA concentrations in hepatic portal venous plasma were proportional to caecal concentrations with very high (> 3 mM) values being recorded in the aleurone group.6. The findings are discussed in relation to the apparent susceptibility of the morphological components of wheat bran to fermentation by large bowel bacteria.

Total parenteral nutrition (TPN) in children is associated with the complicating syndromes of cholestasis and cholelithiasis. The causes of these syndromes are not completely clear. Gastrointestinal hypomotility associated with enteral fasting may be involved in the pathogenesis of both syndromes. We compared weanling rabbits maintained solely on TPN with chow pair‐fed and free‐fed controls over a 10‐day period. Gastrointestinal transit time, assessed with a solid marker technique, was significantly greater in the TPN‐treated animals. No difference in intestinal or biliary bacterial flora was demonstrated by aerobic or anaerobic cultures. Gallbladder bile contained a higher percentage of lithocholic acid, unconjugated bilirubin, and total calcium in the TPN‐treated animals. Markers of hepatic dysfunction were elevated in the serum of the TPN‐treated animals. Mild steatosis and edema were the only histologic differences in the livers of the TPN‐treated animals. We conclude that gastrointestinal hypomotility associated with enteral fasting plays a role in the pathophysiologic changes leading to TPN‐associated hepatobiliary dysfunction. This dysfunction may be mediated by an increase in the absolute and relative concentrations of lithocholic acid in the bile of TPN‐treated animals.
